Comparing:
E202: Potassium Sorbate (Soluble Antimicrobial)
E471: Mono- & Diglycerides of Fatty Acids (Bread Softener)
E202 (Potassium Sorbate) is the potassium salt of sorbic acid, offering 58% water solubility at room temperature. INS 202, group ADI is 11 mg/kg bw/day, widely utilized in beverages, syrups, and cosmetics to block yeast fermentation.
E471 is an authorized food emulsifier composed of glycerol esterified with one or two fatty acid chains (glycerol monostearate / monooleate). INS 471, ADI is Not Limited (Quantum Satis), globally recognized as the ultimate crumb softener and amylose complexing agent in bakery.
